wget and curl, are great Linux operating system commands to download files. But you may face problems when all you have is a dynamic url.
Static url and Dynamic url
From: http://www.webconfs.com/dynamic-urls-vs-static-urls-article-3.php We have:
There are two types of URLs: dynamic and static. A dynamic URL is a page address that results from the search of a database-driven web site or the URL of a web site that runs a script. In contrast to static URLs, in which the contents of the web page stay the same unless the changes are hard-coded into the HTML, dynamic URLs are generated from specific queries to a site's database. The dynamic page is basically only a template in which to display the results of the database query. Instead of changing information in the HTML code, the data is changed in the database.

It would also be a good idea to specify the output filename so, the best way is:
wget 'http://some.site.com/download?id=234&status=download' -O output_filename
